Overwatch

Overwatch is an upcoming multiplayer first-person shooter in development by Blizzard Entertainment. It will feature squad-based combat with two opposing teams of six players each. Players choose one of several hero characters, each with their own unique abilities and role classes.

The four character roles include:
- Offense-oriented characters with high speed and attack but low defense.
- Defense-oriented characters meant to form choke points for enemies.
- Support characters that provide buffs and debuffs for their allies and enemies respectively, such as healing or speed alterations.
- Tank characters that have a large amount of armor and hit points to withstand enemy attacks.

Players can switch between characters in-game following deaths, which is encouraged by the game's overall design.

Unveiled at BlizzCon 2014, the game emphasizes cooperative gameplay using a cast of various "heroes", each with their own abilities and roles within a team. The game entered closed beta in North America and Europe on October 27, 2015, with plans to bring the beta to Asia at a later date. (Source: Wikipedia)
